Abstract

Il est proposé une céramique à électrolyte solide pour applications électrochimiques, ainsi qu'un procédé pour sa fabrication, au moins deux poudres céramiques du commerce étant utilisées, avec différents pourcentages d'oxydes stabilisateurs. Selon l'invention, on obtient ainsi dans un procédé de fabrication simple une céramique à électrolyte solide réunissant les avantages des propriétés des poudres céramiques utilisées, en particulier la haute stabilité mécanique et la haute résistance aux chocs thermiques de la céramique de dioxyde de zirconium partiellement stabilisée, allant de pair avec la bonne conductivité ionique de la céramique de dioxyde de zirconium cubique entièrement stabilisée. La mise en oeuvre, selon l'invention, de la céramique à électrolyte solide dans des détecteurs de gaz garantit une résistance de passage électrolyte solide/électrode réduite et durable.
